Phantom Stage Problem (Pspice Design)

Hi there,Im working on a project which is basically a transductor, connected to a LNA (with an easy Impedance Matching Network between them), and then the load resistor who's reciving the amplification.The fact is that i've introduced a Phantom stage at the end, between the LNA and the load resistor, but it's not working properly.As you may know, the Phantom is useful for using the same pair of cords for power supply and signal comming out.The LNA works fine, and it should put out an 657mV on the load resistor (it works fine without the Phantoms Stages). But, when I connect these stages, the voltage on the load increases until 79 mV, and the power supply for the LNA its not the correct value (it should be 12 v)I've attached a screen capture of the DC simulation in PSpice.Sorry for the arrows, it's easier and faster for me to draw and text in MSPaint, but seems like if i were 6 I hope someone could tell me what's wrong in the circuit, I really don't know why is it not working.Please ask me if you dont understand anything on the circuit.Thank you in advance,Regards.D.
